Traits J - O

Kleptomaniac

This Sim gains the ability to steal anything from any lot as long as no one else is looking. This is a great way to earn some cash early, and there are never any long-term penalties from doing so (no jail sentences or anything like that). However, because being a thief is a lonely job by its nature, it will be tough for a Kleptomaniac to have tons of loot and tons of friends; likely, it'll be one or the other.

This trait is compatible with all others, even Good.

Light Sleeper

In theory, this Sim will wake up faster and react better to anything that interupts his sleep, whether that means the alarm clock or the burglar. In practice, it seems to make little difference, although the Light Sleeper may suffer if he or she is sleeping with a Heavy Sleeper.

This trait is incompatible with Heavy Sleeper.

Loner

Applies a buff when the Sim is by himself, and applies a debuff when many others are around. This also slightly increases the relationship decay until the target is a friend, meaning friendships are pretty tough to maintain with more a few others. You can pair Loner with Charismatic and/or Friendly to slightly offset the penalties, but a Lonely Sim will always prefer their friends with quality over quantity.

This trait is incompatible with Party Animal and Social Butterfly.

Loser

Increases the chance this Sim will lose at any contest, including games and fights. When paired with Unlucky, this Sim is in for a really tough life.

This trait is incompatible with Brave and Charismatic.

Loves the Cold

Increases the amount of time this Sim can stay outside in cold weather without drawing a debuff or freezing solid (thus possibly delaying death). Requires The Sims 3 Seasons to be installed.

This trait is compatible with all others.

Loves the Heat

Increases the amount of time this Sim can stay outside in hot weather without drawing a debuff, suffering sunburn, or spontaneously combusting. Does not affect the length of time the Sim needs to stay outside to draw the "Bronze" buff for having a tan. Requires The Sims 3 Seasons to be installed.

This trait is compatible with all others.

Loves the Outdoors

Applies a buff whenever the Sim is outside. Great when paired with Green Thumb.

This trait is incompatible with Hates the Outdoors.

Lucky

Occasionally applies a 24-hour "Lucky Day!" buff when the Sim wakes up. Increases the chance the Sim succeeds at any game or contest. Increases the chance of having good loot from a tomb while abroad.

This trait is incompatible with Unlucky.

Mean Spirited

Increases the effect of negative social interactions, and applies a buff when a Sim becomes a new enemy. Applies a buff when in a fight, and greatly increases the chance of winning the fight. When paired with Disciplined and a high Martial Arts skill level, it makes the Sim almost invincible. Left to his own devices however, this Sim will have a tough time making friends.

This trait is incompatible with Friendly.

Mooch

Allows the Sim to take food from his neighbors without it being flagged as inappropriate behavior. Also allows the Sim to beg neighbors for change, a social interaction that usually succeeds.

This trait is compatible with all others.

Natural Born Performer

Greatly increases the quality of the Sim's performance when performing as a magician, acrobat, or singer. Does not directly increase the amount of money made, but because the quality of performances are greater, you'll see cash come a little faster. Does not apply any changes to performing for tips.

This trait is incompatible with Clumsy and Coward.

Natural Cook

Increases the XP gain rate of the Cooking skill, decreased the time it takes to learn a new recipe from a book, and prevents the Sim from burning down the kitchen even if he or she has zero Cooking skill. All meals made by the Sim are slightly better quality as well.

This trait is compatible with all others.

Neat

Applies a debuff whenever anything near them is dirty, but allows them to clean even when in a bad mood. This Sim also never leaves a mess when doing an action, such as leaving a puddle on the ground after a shower.

This trait is incompatible with Slob.

Neurotic

Applies a debuff randomly if the Sim worries about whether an object is in a particular state (such as worrying about whether he turned off the sink). Applies a buff when the debuff is fixed (such as checking the sink). This Sim may also interrupt his current action to check an object, even with Free Will off.

You'll need to babysit these Sims carefully. Pairing Neurotic with Absent-Minded will cause a Sim to have some serious disadvantages in getting anything done. If you really want a Sim to be useless, pair those two with Unlucky, Clumsy, and Loser as well.

This trait is compatible with all others.

Never Nude

This Sim wears his or her bathing suit whenever showering or bathing. It must make Woo Hoo pretty tough!

This trait is compatible with all others.

Night Owl

This Sim gains a buff when staying awake past 10pm, and will draw a debuff if he wakes up before 10am. The text description of the trait is a little misleading: the Sim will still naturally want to wake up at 6am unless a job dictates otherwise, regardless of the presence of this trait. You can offset the debuff by just immediately sending the Sim back to bed.

This trait is compatible with all others.

No Sense of Humor

This Sim will always reject another Sim's joke-type social interactions, even from a Sim with the Good Sense of Humor trait. This isn't a tough penalty to overcome, as there are plenty of other ways to increase relationship meters. However, this Sim will find it tough to be friends with a Party Animal or Daredevil when left to the AI.

This trait is incompatible with Good Sense of Humor.

Nurturing

Increases the rate when this Sim teaches a toddler to pee, walk, or talk. When this Sim assists in helping a crying baby, this slightly decreases the decay of the baby's meters. Fantastic trait to be paired with Family-Oriented.

This trait is incompatible with Dislikes Children.

Over-Emotional

Increases the effects and durations of all buffs and debuffs, causing the Sim's overall mood to wildly swing in both directions. If you can maintain happiness, this trait becomes a net positive; if you can't, it becomes a net negative. Good for challenging yourself, if you want to try to be as efficient as possible.
